There are some Chao that are strange and unique! How to get them? Well… that would vary.

Invisible Chao

Breeding a shiny yellow Chao with any color of Jewel Chao can result in something called an invisible Chao. The invisible Chao only has wings, its eyes, its mouth and its emote ball. If it is given animal parts or items, the results will be as visible and permanent as on other Chao.
